Question

Based on this graph what is the rate that co2 increses per year

Answer 1

Given

The graph is given where x -axis denotes year and y-axis denotes carbon-dioxide in ppm.

Step-by-step explanation

To determine the rate that co2 increases per year .

`R=(\Delta CO_2)/(\Delta t)`

Substitute the values from the graph.

`(1980,340),(2000,380)`

`\begin{gathered} R=(380-340)/(2000-1980) \\ R=(40)/(20) \\ R=2 \end{gathered}`Answer

Hence the rate that co2 increases per year is 2.
